I.  Introduction

Europeans called the Americas “The New World.” But for the millions of Native Americans they encountered, it was anything but. Humans have lived here for over ten thousand years. Dynamic and diverse, they spoke hundreds of languages and created thousands of distinct cultures. Native Americans built settled communities and followed seasonal migration patterns, maintained peace through alliances and warred with their neighbors, and developed self-sufficient economies and maintained vast trade networks. Native Americans cultivated distinct art forms and spiritual values. Kinship ties knit their communities together. But the arrival of Europeans and the resulting global exchange of people, animals, plants, and microbes—what scholars benignly call the Columbian Exchange—bridged more than ten thousand years of geographic separation, inaugurated centuries of violence, unleashed the greatest biological terror the world had ever seen, and revolutionized the history of the world. It began one of the most consequential developments in all of human history and the first chapter in the long American yawp. 


II. The First Americans

American history begins with the first Americans. But where do their stories start? Native Americans passed stories down through the millennia that tell of their creation and reveal the contours of indigenous belief. The Salinan people of present-day California, for example, tell of a bald eagle that formed the first man out of clay and the first woman out of a feather. According to a Lenape tradition, the earth was made when Sky Woman fell into a watery world and, with the help of muskrat and beaver, landed safely on a turtle’s back, thus creating Turtle Island, or North America. A Choctaw tradition locates southeastern peoples’ beginnings inside the great Mother Mound earthwork, Nunih Waya, in the lower Mississippi Valley. Nahua people trace their beginnings to the place of the Seven Caves, from which their ancestors emerged before they migrated to what is now Central Mexico. America’s indigenous peoples have passed down many accounts of their origins, written and oral, which share creation and migration histories.

Archaeologists and anthropologists, meanwhile, focus on migration histories. Studying artifacts, bones, and genetic signatures, these scholars have pieced together a narrative that claims that the Americas were once a “new world” for Native Americans as well.


The last global ice age trapped much of the world’s water in enormous continental glaciers. Twenty thousand years ago, ice sheets, some a mile thick, extended across North America as far south as modern-day Illinois. With so much of the world’s water captured in these massive ice sheets, global sea levels were much lower, and a land bridge connected Asia and North America across the Bering Strait. Between twelve and twenty thousand years ago, Native ancestors crossed the ice, waters, and exposed lands between the continents of Asia and America. These mobile hunter-gatherers traveled in small bands, exploiting vegetable, animal, and marine resources into the Beringian tundra at the northwestern edge of North America. DNA evidence suggests that these ancestors paused—for perhaps 15,000 years—in the expansive region between Asia and America.1Other ancestors crossed the seas and voyaged along the Pacific coast, traveling along riverways and settling where local ecosystems permitted.2Glacial sheets receded around fourteen thousand years ago, opening a corridor to warmer climates and new resources. Some ancestral communities migrated south and eastward. Evidence found at Monte Verde, a site in modern-day Chile, suggests human activity began there at least 14,500 years ago. Similar evidence hints at human settlement in the Florida panhandle at the same time3 On many points, archaeological and traditional knowledge sources converge: the dental, archaeological, linguistic, oral, ecological and genetic evidence illustrates a great deal of diversity, with numerous different groups settling and migrating over thousands of years, potentially from many different points of origin.4 Whether emerging from the earth, water, or sky, being made by a creator, or migrating to their homelands, modern Native American communities recount histories in America that date long before human memory.

In the Northwest, Native groups exploited the great salmon-filled rivers. On the plains and prairie lands, hunting communities followed bison herds and moved according to seasonal patterns. In mountains, prairies, deserts, and forests, the cultures and ways of life of paleo-era ancestors were as varied as the geography. These groups spoke hundreds of languages and adopted distinct cultural practices. Rich and diverse diets fueled massive population growth across the continent.


Agriculture arose sometime between nine- and five-thousand years ago, almost simultaneously in the Eastern and Western Hemispheres. Mesoamericans in modern-day Mexico and Central America relied upon domesticated maize (corn) to develop the hemisphere’s first settled population around 1,200 BCE.5 Corn was high in caloric content, easily dried and stored, and, in Mesoamerica’s warm and fertile Gulf Coast, could sometimes be harvested twice in a year. Corn—as well as other Mesoamerican crops—spread across North America and continues to hold an important spiritual and cultural place in many Native communities.
